積層体及び真空断熱材
Document Type and Number:
Japanese Patent JP7087462
Kind Code:
B2
Abstract:
To provide a laminate that can be used as an exterior film with no deterioration in gas barrier properties even if a vacuum heat insulation material is deformed.SOLUTION: A laminate includes a base material film 11, a first gas barrier layer 12, a second gas barrier layer 13 and a sealant layer 14 in this order, and the layers 11, 12, 13 and 14 are bonded respectively interposing acrylic pressure sensitive adhesive layers a1-a3. When a vacuum heat insulation material with a core material sealed using the laminate as an exterior film is bent by applying to an outer wall material, etc. of a curved shape, gas barrier properties can be maintained and thermal insulation performance of the vacuum heat insulation material can be maintained.SELECTED DRAWING: Figure 1
